dont bother with the 351m, good truck engine dont get me wrong, but for strictly performance they are lacking. they have a really low compression ratio around 8-1 which is horrible for performance. stick with a windsor or a cleveland, and dont confuse the cleveland with the m they are radically different animals. any other questions just ask
